Guardian Concept Uses Lasers to Tell Pedestrians When to Cross

Thousands of people lose their lives each year to car accidents. The sad thing is some of these deaths could have been prevented, had they taken more care when crossing the road. We can only do so much by raising awareness. The second step is coming up with a system to force people to be aware of their surroundings, so they will only actually attempt to cross the road when it’s safe. That’s where the Guardian comes into play.

Ho-Joon Lim’s simple, but smart concept uses laser lights to guide people on their short walk across the street. It also works effectively to keep people off the streets and on the sidewalk when it’s not time to cross the road yet.

The only real challenge with the design is that you need some sort of fog or smoke in the air to make low-power laser beams visible – especially in daylight. So unless you live in a really foggy city, or the design incorporates a smoke machine, it might not be too practical.
